Error Handling Strategies for Automotive Networks 880587

A significant portion of communication in Automotive Networks consists of signals, which are vital to the safety of the vehicle. In addition to requirements resulting from the actual transfer of information an Automotive Communication Protocol has to incorporate properties which ensure operational safety even in presence of errors. Based upon a discrimination into reversible errors and irreversible failures, defect nodes have to be determined and subsequently disconnected from the network. In this paper proper schemes for error detection, report, recovery and confinement are presented.
